NKammerer The best hostel I have ever stayed in, by far. I paid for a 12-bed suite but the suite was divided into smaller rooms, so there were only 3 beds in my room. The staff is incredibly friendly, and single travelers are welcomed into the group immediately. I'm not a huge partier, and it's not necessary to be one to enjoy the Madhouse. It's quiet enough to get a good night's sleep, but there is an event on every single night, and all are encouraged to participate. The kitchen is fantastic - incredibly well equipped, and the "family dinners" were a highlight of my stay. Centrally located and easily accessible by tram or metro. The only downside is that the kitchen opens at 9am. So if you want an early start, you'll have to plan on breakfast elsewhere.

naganoogie I had an ensuite doubleroom for a week. And it's been one of the nicest hostel I've been in terms of cost and facilities.
Besides the usual amenities, the doubleroom, which is clean and modern also includes a barfridge, a little kitchenette (though without any cooking utensils nor cutleries) and a small balcony.
Staffs were friendly and helpful, with good knowledge about the wheres and whats of Pragie. Public transports (both tram and metro) were easily within reach from the hostel, and close to both Old and New Towns of Prague.

jonas.boon Our stay in the Art Hole Hostel was really epic! This was the best Hostel we´ve ever been: very nice people, good service and the guy there (a kind englishman named Luke) told us about a lot of good places to go and even sent us to a beautiful town nearby.
Art Hole rocks!

jenniesue This hostel is fairly small and is located on the 2nd floor. The rooms were large and clean. Bathrooms and showers were down the hall and both were very clean. There is a common room with TV and kitchen facilities, as well as one computer with free internet access. The location is a couple of blocks from the metro stop/streetcar and a large grocery store. It is an easy walk in the old town/city center and to Wenceslas Square. I did notice that there are other hostels that are more convenient to the tourist areas of town, but overall this hostel was quite comfortable and I would stay here again.
